The rated input current of submersible motors is higher than the rated
input current of standard motors.
Select an appropriate drive according to its rated output current. When the
distance between the motor and drive is long, use a cable thick enough to
connect the motor to the drive to prevent motor torque reduction.
When an using an explosion-proof motor, it must be subject to an
explosion-proof test in conjunction with the drive.
This is also applicable when an existing explosion-proof motor is to be
operated with the drive. Since the drive itself is not explosion-proof,
always install it in a safe place.
Do not use a drive for a single phase motor.
Replace the motor with a three phase motor.
If an oil-lubricated gearbox or speed reducer is used in the power
transmission mechanism, oil lubrication will be affected when the
motor operates only in the low speed range.
The power transmission mechanism will make noise and experience
problems with service life and durability if the motor is operated at a speed
higher than 60 Hz.
